Abstract: A pump bearing for use in a gear pump including a top face, a side face perimetrically surrounding the top face, a bottom face opposed to the top face, a first bearing bore projecting from the top face to the bottom face defining an axis and configured to contain a drive-side shaft, and a groove within the side face located between the top face and the bottom face a variable depth in a direction perpendicular to the axis configured to a receive seal.

Abstract: A pump bearing including a top face, a side face peripherally surrounding the top face, a bottom face opposed to the top face, a first bearing bore projecting from the top face to the bottom face, an edge defined where the top face meets the side face, and an asymmetric pressure balance groove defined within a portion of the edge of the top face and the side face defining first depth from the top face.

Abstract: A method of using an apparatus for producing electric power or mechanical drive in which fuel gas produced in a gasifier using air as an oxidant is supplied to the gasifier by extraction from the exit of the air compressor of a gas turbine.

Abstract: An apparatus for binding a three-dimensional load with tape comprises a turntable for rotating the load, a tape dispenser and a logistical controller. The tape dispenser is moveable relative to the turntable and the load. The detector detects the top of the load, and is moveable with the tape dispenser. The logistical controller is arranged to control rotation of the load and movement of the tape dispenser. In particular, the controller is arranged to operate the apparatus to dispense the tape according to a predetermined default pattern until the detector determines the top of the load. Once the tope of load is detected, the controller is arranged to operate the apparatus according to a corrected pattern based upon the detected top of load.

Abstract: A fuel preparation apparatus in which coal or coal and other carbon containing material is converted to an environmentally acceptable fuel gas by the reaction with air and steam at a pressure of from 20 to 90 pounds per square inch absolute suitable for providing fuel to a gas turbine, or a stoker type or other boiler having a coal delivery system, a coal crusher, coal storage bins, lock hoppers, a gasifier vessel of two stages, liquid and solid separator vessels, heat and steam recovery vessels, equipment to control the flow of steam and air to the gasifier so as to maintain fuel quality, and a gas clean up plant that will remove environmentally unacceptable components of the gas such as hydrogen sulphide and other sulphur containing compounds and tars and light oils.

Abstract: A gravure method for applying a discrete patch (12) of uniform coating to a moving web (14) includes defining a nip area (20) between a gravure roller (16) and a backing roller (22), moving the gravure roller to the nip to a precise lengthwise location on the web, and moving the gravure roller from the nip. The method is improved by controlling the speed of movement of the gravure roller to the nip, and controlling the speed of movement of the gravure roller from the nip thereby producing a discrete patch.

Abstract: A method and apparatus is disclosed for gravure coating a liquid reactive with the atmosphere onto a web. The gravure apparatus comprises an engraved gravure cylinder, an impression roller backing the web and pressing it onto the gravure cylinder to form a nip, a curtain or jet formation means to wet the surface of the gravure cylinder, and a doctor blade means for wiping excess coating liquid from the surface of the gravure cylinder prior to the nip. A shroud encompassing the gravure cylinder and the curtain or jet formation means creates a first zone between the nip and a partitioning baffle extending from the shroud, a second zone between the partitioning baffle and the doctor blade means, and a third zone between the doctor blade means and the nip. A gas non-reactive with the coating liquid is supplied to each zone by a gas distribution means such that the reaction rate of the coating liquid with the atmosphere is greatly reduced and the curtain or jet is not disrupted.

Abstract: A rigid handcuff (FIG. 3) includes a pair of separate lockable bracelet members (16, 18) each having a respective plate-like extension (30, 32) each of which abuts the other at end face along a line normal to a longitudinal axis of the handcuff, the line and the axis lying in the common plane of the bracelet members. A respective plate-like connector (38) overlies the abutted extensions (30, 32) with the outer ends of each connector (38) abutting against a respective bracelet member (16, 18). The extensions (30, 32) and the connectors (38) ensure that the bracelet members are restrained against all movement relative to one another thereby providing a rigid handcuff assembly. A cover assembly comprising a pair of opposed plastic cover members provides a rigid grip for the handcuff intermediate the bracelet members.

Abstract: A baton, e.g. for use by police, has a shaft and a handle, the handle being movable relative to the shaft between a first position in which it is generally in line with the shaft and a second position in it extends transversely to the shaft. A further handle is extendible when the first handle has been moved to extend transversely, and the shaft of the baton also may be extendible. Thus the baton is convertible from a compact straight configuration to a side-handled configuration.
